Introducing the AAC 5.56mm 16” Multi Purpose Weapon (MPW). The AAC mid-length gas 5.56mm MPW has been designed for the highest levels of reliability. The full-auto bolt carrier is custom machined to be the correct final dimensions to allow for a thicker-than-typical for the industry nickel-boron coating for both added corrosion resistance and a hard surface finish to facilitate ease of cleaning.

The carrier-key is heat-treated for durability and is properly staked. The black phosphated bolt is machined from mil-spec Carpenter 158 steel and is shot-peened for durability, and then high-pressure tested.

The extractor spring is made from upgraded 383,000 psi steel for the longest life, and the green o-ring has been tested to -40C degrees. AAC 5.56mm MPW barrels use 1/7 twist rifling, and the entire barrel, bore, and chamber are finished in corrosion resistant SCARmorTM to provide a high surface hardness for longevity without impeding accuracy.

The barrel is protected by a KAC URX-3 handguard with MIL-STD-1913 accessory attachment points. The pictogram-marked lower receiver features a Geissele two-stage trigger. The rifle also features a six-position mil-spec receiver extension with a propely-staked castle nut and Magpul stock, pistol grip, and trigger guard.

freaking sweet action,
October 26, 2016

Bought this rifle 2 months ago and couldn't be more satisfied with how it functions. The rubberized grip was perfect for my hand, the Knight's Armament quadrail was exactly as you would expect from such a high quality manufacturer. The buttstock is a solid edition as well, fits in the pocket of my shoulder well. The only negative side is that they discontinued making these so if you find one, buy it.
